- GRAPHOPHONE-REQORD BLANK.

No Drawing. 7 I Applicationflled January 3, To all whom it may concern; Be it known that I, WALLACE APPLETON BEATTY, a citizen, of the United States, re-

-siding at New York, inthe county of New York and State of New York, have invented certain new. and useful Improvements in -Graphophone-Record Blanks; and I do.

hereby declare the following to be a full, y

clear, and exact description of the invention,

such as will enableothers skilled in the art to which it appertains to make and use the V same.

- This invention relatesto' plastic products,

and especially to graphophone records made from a novel compound to be disclosed begraphophone record which will not produce the foreign noises which are common to the present graphophone records, and will on .the other hand, be more durable and lesss liable to wear than those which have heretofore been proposed. I V

'To'these ends the invention consists in the novel articles of manufacture composed of the novel compositions of matter more fully hereinafter disclosed and particularly pointed out in the claims. 1 s

i In order tlfat this invention may be more clearly understood, it is said :'-In my prior application #702,046, filed June 6,1912, en-

titled Artificial gums and process of producing thesame, I have disclosed and claimed a "new-gum and method .of making it, which method, when] briefly stated, consists in forming a new compound from a mixture of acetone and phenol to which is added a small quantity of acid, in order to produce what I believe to be dioxy diphenyldimethyl: methane. This new compound is then. further acted upon, as stated in. said application above, by formaldehyde, inorder to produce a further tenacious product constituting the said new .gum above mentioned. This new gum'is found to beinodorous, in-- soluble in water, is relatively strong and tenacious, and it may be colored with dyes or with other substances, I find further that this new gum when first produced, is more or less soluble in alkali; that-it becomes less andless soluble after it has been'heated at say 100 C., until when it has been kept. at that temperature for say two hours, it is scarcely soluble at all even in strong alkali.

tures into a'mass which is insoluble in alkali. I I find the gum is also soluble in alcohol,

ether, acetone, glacial acetic acid, amylalcohol, amyl acetate and acetylenetetrachlorid, or mixtures of these; It is, however, insoluble in oils, such as linseed oilf P l and mineral oils. When in its V insoluble condition, it. is an inodorous trans- 7 parent mass quite strong, non-brittle and tenacious, It is also quite hard an'dwill not burn unless kept continuallyin 'theflame. 'In this condition of the .gum, I have not found any solvent fem: I

Y As an alternative method of making, the

gum insoluble, I may produce a solution of the same, out of one or more of the above solvents, and add suflicient acid to give to the said solution an acid reaction, rather than an alkaline one, whereupon I have discovered that the gum, upon drying, will itself go peratures; Y

, In order to make graphophone records out of this new gum, Isimply dissolve-it to the proper consistency, preferring to form therefrom a plastic mass,'an dmold the same into into its insoluble condition at ordinary tem-' the proper shape, whereupon the molded mass may be subjected to the usual process of recording speech, music, or other sounds,

and it may theneither be heated under the proper conditions'to, render it hard and insoluble, or if it has been made acid, as above stated, it may be left to dry at ordinary temperatures, whereupon it will become a hardv and insoluble mass. I have found whether I employ the heating step or the acid step to secure the hard condition of the gum, it v is, sometimes desirable to carry it out at a pressure'less'than that'of the atmosphere in order to remove the last traces of the solvent.

I have further found that the gum in assum- 1' tically non-inflammable records which are not acted upon by moisture, acids, and other reagents. They are further-not sensitive to Furthergum, as above intimated, will produce pracchanges in temperature, and therefore, the of" celluloid. This cellulose mixture is records produced from my gum are not subjected tothe usual warping and distortions frequently encountered during shipment,

owing to. the fact that the records are subjected, to an undue temperature either in storage or in transit.

In addition. to the use of the gum itself for the above purposes, I mayalso, and m fact prefer to, fill this gum with a. finely divided hard substance, such as very finely divided graphite, finely divided wood powv der, lamp black, steel dust finelydivided, or

oxid of iron, such as, for example, Fe Q etc. The filling of the gum is easily accomplished either. by making the gum into a relatively thin solution, thoroughly stirring the same and letting it set, or even by making a more 'plasti mass and thoroughly working the filler r fillers into it. I further find both when'making the records out of the pure gum, as well as whenmaking them out of the filledgum, it is desirable to subject the finished molded mass to a considerable pressure in a hydraulic press in order to properly solidify the mass, as well'as to exclude air bubbles.

' of seventy-five parts of the acetate to twentyfive parts of the dioxy-diphenyl-dimethylmethane. This mixture is readily accomplished by dissolving its constituents in a common solvent, such asacetone, and allowing it to set. The mixture may be then either used in its relatively pure condition, or it may b e"likewise filled, as mentioned above, with various substances. I also prefer to solidify the finished molded product by pressure, as stated in connection with the gum. I

Not only mayI employ the mixture just stated, but I find it furtheruseful to employ, under certain conditions, a mixture composed of say twenty-five parts of the dioxydiphenyl dimethyl-methane to say seventyfive parts of nitro-cellulose, such as the trinitrocellulose employed in the manufacture treated in all respects like the first men tioned mixture. I

In addition to recordino: directly upon the new mass constituting. the graph'o hone diethyl-ketone; by the term phenol I mean to include only carbolic acid and the cresols; and x by the ter-m aldehyde I mean to include only formaldehyde or its polymers, or its ammonia condensation productssuch as hexamethylene-tetra-amin and acct-aldehyde.

It is obvious that those skilled in the art may vary the details ofthe procedure without departing from the spirit of my invention, and further, that homologues of the compounds mentioned may be employed, and still come Within the spirit of my invention. Therefore, I do not wish to be limited to the above disclosure, except as. may be required by the claims.
